6DescriptionCVE.org
A security vulnerability has been detected in UTT 进取 520W 1.7.7-180627. Impacted is the function strcpy of the file /goform/formConfigDnsFilterGlobal. Such manipulation of the argument timeRangeName leads to buffer overflow. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Buffer overflow in the DNS filter configuration interface of UTT 520W firmware 1.7.7-180627 allows adjacent network attackers with low privileges to cause denial of service by submitting an overly long timeRangeName parameter. Public proof-of-concept code is available, but exploitation requires authenticated access from the local network. The vendor did not respond to disclosure and no patch is available.
